You can divide the users added to your site into user groups. User groups are used in all views in the user filter. With groups, you can easily add a group on team members or multiple teams in your company to an event, for example. One user can belong to several groups at once, for example, Management and the Marketing Team.
To add a new user group go to Settings > Administration > Users and groups and click on Add group.Enter the group name and select members.To modify or delete a group, click on its name.Here you can select or deselect users, or delete the whole group, if not needed anymore.
